Hi ! Thank you for your support. I really dont care about the bells I lost, but I'm sad that he made me a bad reputation even if that's totally his friend's fault (or maybe him...I found strange that he asked me "what do to if the code doesn't work" before buying it. Seems like he planned to tell that it doesn't work... I don't accuse him because he didn't use the code, but maybe his friend was late and the public demo is available today, so he maybe wanted his bells back because he didn't use the code... Well that's just my thoughts.)
